IIS vs Nginx

Developers should learn IIS when building or deploying web applications on Windows-based environments, especially for enterprise solutions, intranet sites, or services requiring tight integration with Microsoft technologies like meets pick nginx when you need a battle-tested reverse proxy or static-file server in front of a monolith or a handful of services and you're fine hand-writing config — its epoll-based core still edges out caddy and traefik on raw static-file throughput in most 2026 third-party benchmarks. Here's our take.

IIS

Nice Pick

Developers should learn IIS when building or deploying web applications on Windows-based environments, especially for enterprise solutions, intranet sites, or services requiring tight integration with Microsoft technologies like

Pros

• NET, SQL Server, or Active Directory
• Related to: asp-net, windows-server

Cons

• Specific tradeoffs depend on your use case

Nginx

Pick nginx when you need a battle-tested reverse proxy or static-file server in front of a monolith or a handful of services and you're fine hand-writing config — its epoll-based core still edges out Caddy and Traefik on raw static-file throughput in most 2026 third-party benchmarks

Pros

• Don't pick it for Kubernetes-native microservices with rotating pod IPs — Traefik's CRD-based service discovery beats hand-reloading nginx configs on every deploy
• Related to: docker, kubernetes

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. IIS is a platform while Nginx is a tool. We picked IIS based on overall popularity, but your choice depends on what you're building.

The Bottom Line

IIS wins

Based on overall popularity. IIS is more widely used, but Nginx excels in its own space.
